What Is Chemical Energy 

Chemical energy is a very important type of kinetic energy that has many biological and mechanical uses. When two or more compounds mix a chemical reaction will occur as all the compounds struggle to be in a state of equilibrium.

How to Calculate the Heat Produced from Chemical Energy

When a chemical reaction occurs and tries to make both compounds reach equilibrium, heat is released as the compound is created. This heat may cause issues and may even break specific instruments used in the mixture, thus making it very important to know the amount of heat produced by the reaction.

1.) Write the Formula

Begin by writing the formula for the heat produced and transferred in a chemical reaction. This formula will be Q = mcΔT, where Q is the heat transferred in Joules (J), ΔT is the change of temperature(OC), m is the mass in the reaction (kg), and c is the heat capacity of the mass. (J/kgOC)

2.) List Down the Given Numbers and Convert them Appropriately

After writing down the formula, you will now have to list out the given numbers to help you visualize the overall equation. Not only that but you will need to convert the given numbers to the appropriate unit of measurement. This means that if the change in temperature is in Fahrenheit (OF) then you must do the necessary conversion required to change the unit to Celsius. (OC)

3.) Substitute the Given Numbers into the Formula

When you have finished writing down and converting the given numbers to the appropriate units, you will now need to substitute said numbers into the formula. This will help you easily have a reference to the overall equation, and can concisely explain how you came to the answer.

4.) Answer the Generated Equation

After substituting the given numbers, you will now need to answer the generated equation. This means that you will need to do the necessary calculations to arrive at the change transferring in heat

5.) Convert the Answer if Needed

When you have obtained the answer in Joules, you may need to do specific calculations to convert them to the unit of measurement asked by the question. If not, then you may skip this step.

FAQs

What is the chemical potential?

Chemical potential is the amount of potential energy when one of the substances is subjected to a chemical reaction or a chemical mixture. The higher the chemical potential the greater the amount of chemical energy the reaction will release. The inverse is also true, which means that the lower the chemical potential the lower the proportional release of chemical energy from the chemical reaction or mixture. This concept is used in the prediction and determination of corrosion of a specific material when it is placed in a chemical mixture and reaction. Not only that but chemical potential can also be used to help determine the disequilibrium of both chemicals in the chemical mixture, which causes the chemical reaction.

How do nuclear chemicals produce chemical energy?

Nuclear chemicals cause the reaction of fission which converts the chemical energy to nuclear energy. This type of energy is the most efficient source of power or electricity. Nuclear fission is the chemical reaction of Uranium splitting into two smaller atoms, which causes the energy stored in said atom to be released. Nuclear energy is a product of the heat produced by chemical energy, basically indicating the transition of one type of energy to another. This heat is too strong and may cause specific meltdowns if not properly maintained and cooled down.

What is a simple example of chemical energy?

There are many examples of occurrences of chemical reactions that create chemical energy in our everyday lives. One example can be seen in the conversion and absorption of the food we eat into energy and nutrients. Specific compounds in our body break down the food we eat and allow our body to absorb and inculcate the various nutrients generated by the compounds. Another simple example of chemical energy is the striking of a match or the creation of a fire through a lighter. These two similar examples create fire via friction of specific compounds causing fire to appear.

Chemical energy is a type of kinetic energy that is created when two or more compounds or elements mix. When a chemical reaction occurs, the mixture produces both heat and a new substance or compound with some of the properties of the mixed compounds. Not only that, but a chemical reaction may need an outside source or medium to conduct said mixture and reaction.
